I have been mining on this pool for months now and I must admin, no issues so far. Payments are regular.
I simply don't understand why bother mining elsewhere. If you look at the 30 day chart, you see that NiceHash pays 1.5% more than Bitcoin mining. It is pay per share pool and it has 2% fee. That makes it -0.5% less than Bitcoin mining or in other words - as a 0.5% fee PPS pool. No other pool can survive this on long term. And I didn't consider the 10 fold payment increase that lasted whole week in december.
I don't even set p parameter. Because on long term, NiceHash pays more and additional pool switching just causes troubles with my antminers.
Whoever thinks that there are better paying pools out there should do the math and recalculate again.
Since nicehash is actually a proxy pool, you are not mining directly on the actual upstream pool. You are assuming there is no hit to performance by doing this. I've been trying to help someone with a large farm debug why they take a massive reject hit which far more than offsets the fee at certain times on nicehash and the fact it's a proxy pool is the only valid explanation. I've seen it do some funky mining with restarts every 3 seconds - no mining hardware can work efficiently with that.
Buyers of hashing power at NiceHash/WestHash are not only mining Bitcoin, they are also (sometimes) mining various other coins. Some of them are still at very low difficulty, switching jobs very fast, etc. Unfortunately manufacturers of ASIC miners are putting very weak controllers in their miners (saving a few $ in a machine, worth hundreds even thousands of $
) with non-optimized software and are thus unable to process large number of shares/jobs/work-restarts. A typical example was KnC Titan (not SHA256, but an Scrypt miner) which was only able to mine Litecoins until the controller software was properly optimized. Recent example of a SHA256 miner that is having a few issues with rejects is AntMiner S5, hopefully Bitmain will improve it soon. If manufacturers would put a multi-core Raspberry Pie 2 in their miners (with a good controller software - I'm not talking only about cgminer/bfgminer, but also drivers, etc. handling of low difficulty coins, switching jobs very fast, proper handling of flushwork, etc.) there would be no issues. For example, there are no issues with sgminer mining any GPU based coin, running on PC (which always has a decent CPU). Probably there is also room for improvement in cgminer itself for these issues.
Anyway, we are aware of these issues and we've implemented measures to mitigate these issues a long time ago. We are rewarding providers (sellers) with extra shares paid by buyers when fast work restarts happens. If you are a seller it is very important for you to
monitor the average mid-term hashrate, reported on our website (it is calculated from shares, rewarded to your miner) and the actual earnings, not only the hashrate or accept/reject ratio that is displayed by your miner hardware/software, since in some cases you will be
rewarded for more then your miner is showing you in terms of hashrate. Details are explained in
this FAQ.
